Application June 9, 1945, Serial No. 598,614

- 1 Claim.

This invention relates to an adjustable electric lamp. The adjustablestands or supporting arms of known construction for electric lamps,possess the drawback that the ball and socket joints and screw boltslimit the movability and are liable to damage the electric leads. It hasbeen proposed to employ braking and sliding devices as means forsecuring adjustable stands in the adjusted position, but they possessthe drawback that locking screws are necessary which at the slightestvibration change the position, the thread of the screw or nut becomingworn when frequently used.

It is therefore the primary object of the present invention to provide afloor or table lamp which can function as either an ordinary table lampwith comparatively easily adjustable incandescent lamps, or as a floorlamp which has a highly attractive appearance and which looks more likean ornamental luxurious lamp rather than like a utilitarian adjustablelamp that combines two lamps to one.

Another object is to provide a lamp which performs the various functionsabove enumerated without requiring much space and without necessitatinga freakish or unconventional appearance.

Yet still another object of the present invention is the provision of adevice of the character described which is light in weight, simple inconstruction and inexpensive to manufacture, so that it can be sold at avery reasonable price.

Further objects of the instant invention reside in any novel feature ofconstruction or operation or novel combination of parts present in theembodiment of the invention described and shown in the accompanyingdrawing whether within or without the scope of the appended claim andirrespective of other specific statements as to the scope of theinvention contained herein.

In the drawing:

Figure l is a front elevation of a preferred embodiment of my invention;

Figure 2 is a side elevation of the same; and

Figure 3 is a detailed sectional view on the line 33 of Figure 1.

Similar numerals refer to similar parts throughout the several views.

In the drawing the numeral l denotes a base which is preferably hollowand conical, and from whose center extends upwardly the lowest telescopemember of a hollow center post that can be telescopically expanded asindicated in Figure 1 in dash-and-dotted lines. A head 4 is secured tothe uppermost telescope member 3, and curved figures 5 (which areS-shaped in the instance shown) are laterally secured to head 4 and areconnected to each other by means of an ornamental oblique cross-bar 6.An electric lamp having a shade and a switch is carried by the topportion of each figure 5. The figures 5 are hollow and their outerportions are provided with slots [0 One or more coiled cables I l, whichare provided with a contact plug it 4, are extended through base ll,through the telescopically expansible center post (2 and 3), through thefigures 5 and through the T-shaped members 9.

If the center post parts 2 and 3 are in the position shown in Figures 1and 2 in full lines, the lamp can be used as a table lamp; if the centerpost is expanded, as indicated in dash-and-dotted lines in Figure 1, thelamp can be used as a floor lamp.

While there has been shown and described and pointed out the fundamentalnovel features of the invention as applied to a single modification, itwill be understood that various omissions and substitutions and changesin the form and details of the device illustrated and in its operationmay be made by those skilled in the art without departing from thespirit of the invention. It is the intention, therefore, to be limitedonly as indicated by the scope of the following claim.

Having thus described my invention, what I claim and desire to secure byLetters Patent in the United States is:

In an electric floor and table lamp, the combination of a hollow,telescopically expansible center post having a hollow base at its lowerend and a head at its upper end; with two curved T-slotted tubularmembers laterally extended from said head and carrying electric lamps attheir top portions; and T-shaped members slidably engaging the slottedportions of said tubular members and carrying electric lamps which areconnected to a source of current by means of coiled cables that areextended through said base, centerpost, head, and figures.
